Hi All,

Does anyone have any suggestions on improving the performance of ETL
scripts.

I am trying to transform the raw XML data into our models. The data is
split across several files totaling approx 40mb. So far the transformation
has being running for over 26hours and is only approx 8mb through. (The
current file is 9mb and has taken 24hours on its own so far.)

It also looks as if Eclipse will not maximise the processor usage. I have
a Dual Core processor but both processors only seem to be running at 50%
whilst it is processing the Transform.

I'm reluctant to stop the process even though it looks like taking a week
as I don't want to havve to restart it if there are no known performance
tweeks.

Thanks for any suggestions,

Darren
